WikiLeaks founder Julian Assange said documents taken by National Security Agency leaker Edward Snowden will still be published.

"There is no stopping the publishing process at this stage," Assange told ABC's This Week Sunday.

Assange also called Snowden a "hero" and said he doesn't know where he is or where he plans to go.

The Guardian newspaper reported that Secretary of State John Kerry had called Ecuadorean President Rafael Correa to ask him to turn down any asylum requests. Sunday morning, The Associated Press reported that Correa said Snowden is "under the care of Russian authorities," and he's still stuck in Moscow without a U.S. passport.

Last week, the Obama administration indefinitely delayed a decision expected to end tariffs on imports of roses from Ecuador -- at a price of about $250 million a year.

In the meantime, chairman of the House Homeland Security Committee Michael McCaul, R-Texas, said Snowden stands as an example of why there needs to be a "civilian interface" for the thousands of Americans with security clearances who work with top-secret information, adding that the interface must come with "robust security."

Snowden, he said, hadn't been a "stellar student" but had been allowed access to state secrets. McCaul spoke on C-SPAN's Newsmakers program Sunday.

"I kind of question who we're giving access to, and we should take another look," said McCaul, who has complained that only the Intelligence Committee handles oversight of classified information. McCaul would like his committee to have access so that members may have a debate about what civilians are allowed to see, even as both Republicans and Democrats have worked to further limit access so that it can't be leaked.

Germany's Der Spiegel newspaper reported that its reporters have seen documents leaked by Snowden showing that the NSA conducted online surveillance of European citizens and appears to have targeted European Union buildings.

The documents appear to show that the U.S. government bugged embassy buildings in Washington, D.C., and also infiltrated the European Union's computer network, the paper reported. One document from September 2010 "explicitly names the Europeans as a 'location target,'" the paper reported.

The president of the European Parliament, Martin Schulz, told the Associated Press that he was "deeply worried and shocked" about the allegations of U.S. authorities spying on EU offices.

"It would be an extremely serious matter which will have a severe impact on EU-U.S. relations," he said.

The documents show the United States may also have targeted phone calls made at the Justus Lipsius Building in Brussels, where the EU Council of Ministers and European Council are located, The Guardian reported.

Germany's justice minister, Sabine Leutheusser-Schnarrenberger, accused the United States of using "Cold War" methods against its allies, AP reported.

"If the media reports are accurate, then this recalls the methods used by enemies during the Cold War," Leutheusser-Schnarrenberger said in a statement to AP.

On Sunday, politicians again called for Russia's President Vladimir Putin to turn Snowden over to U.S. Authorities.

"This is a direct slap in the face to the United States of America," Sen. John McCain, R-Ariz., told Fox News Sunday.

President Obama said Thursday that he won't engage in "wheeling and dealing and trading" to get Snowden extradited to the U.S. However, he said he was "concerned" about what else Snowden plans to leak.
